Automatic mechanical device for shaft and sleeve cooperation

Abstract

The invention relates to an assembling device of mechanical parts and in particular relates to an automated mechanical device with matched shaft and sleeve. The automated mechanical device is composed of a pneumatic device, a pressure block, a rotating shaft, a sliding groove, a connecting rod, a cam, a cam shaft, a grooved wheel mechanism, a main shaft, a spring clamping jaw, a material pushing plate and the like; the grooved wheel mechanism is arranged on the main shaft and the cam shaft, the grooved wheel mechanism is connected with the main shaft by a general flat key, an indexing turn plate is arranged on the main shaft, the spring clamping jaw is arranged right above the indexing turn plate, the spring clamping jaw is arranged at the tail end of the sliding groove and is positioned right below the pressure block, a stepped shaft is arranged in the sliding groove, the pneumatic device and the pressure block are arranged above the sliding groove, and the sliding groove is arranged obliquely. According to the automated mechanical device, the manual labor intensity for assembling the shaft and the sleeve can be alleviated greatly, the working time is saved, and meanwhile, the labor productivity can be improved greatly. The s automated mechanical device has the advantages of exquisite structure, high automation degree, accurate transferring position, consistent pressure and high assembling precision, and the parts requiring interference fit can be assembled rapidly.

Description

technical field [0001] The invention relates to an assembly device of mechanical parts, in particular to an automatic mechanical device in which a shaft and a sleeve cooperate. Background technique [0002] In current industrial enterprises, such work is often encountered. The fit between the shaft and the sleeve is an interference fit. If it is manual assembly, it must be beaten with a hammer to beat the shaft or the sleeve so that they are tightly assembled. Such work is relatively heavy and is usually manually operated, which is difficult for continuous production. It is very wasteful of manpower, and the efficiency is low. Manually doing certain repetitive tasks for a long time is prone to fatigue. It is very headache when encountering such work. In large-scale machinery factories, there is also a hydraulic method to compress the shaft and the sleeve, but the use of hydraulic devices often requires a large investment and high cost, which is difficult for small enterpris...

AI Technical Summary

Problems solved by technology

This kind of work is relatively heavy, usually manual operation, difficult to continuous production

It is a waste of manpower and low in efficiency. Manually doing certain repetitive tasks for a long time is prone to fatigue. When encountering such work, it is very headache

In large machinery factories, hydraulic pressure is also used to compress the shaft and sleeve, but the use of hydraulic devices often requires high investment and high cost, which is difficult for small enterprises to accept.
